cometary panspermia. 2019

in 2018 a mysterious object from outside our solar system passed by our planet. by the time earth's telescopes registered it's existence, it was gone. scientists were puzzled by the images it left behind. was it a comet? debris from a galactic battleground? an alien space craft? perhaps the aliens were tiny microbes from beyond the galaxy that are even now raining down upon our earth, poised to make us the mutants we must become.
